Product Description:

The R46GENA-TS-NS-VS-00 is a brushless servo motor produced by Pacific Scientific within the R Servomotors series. It serves as a rotary actuator in industrial automation systems, delivering commanded motion for tooling tables, material-handling axes, and packaging equipment through closed-loop drive control. Brushless operation eliminates brush wear at the commutator and supports consistent performance during repeated start-stop motion. The motor is supplied without a holding brake, so any load that must remain fixed during power loss requires drive torque or an external locking method.

The motor delivers a continuous stall capability of 7.6 Nm, meaning it can hold that torque continuously without overheating under rated conditions, while transient demands can reach 20.2 Nm of peak torque for acceleration or disturbance rejection. A rotor inertia of 0.40 kg·m² × 10⁻³ helps balance responsiveness and stability in servo loops, so the axis can react quickly without becoming difficult to tune. The motor has a 4.25-inch square frame and a stack length of 6 inches, allowing installation on common inch-based machine layouts and giving the housing enough active length for the listed torque range. It uses a standard housing and a standard winding type, which keep the mechanical and electrical configuration straightforward.

Motion feedback is generated by a Tachsyn transducer, which provides tachometer and resolver signals for velocity and position control, and no secondary feedback device is fitted. Torque production uses rare earth (samarium cobalt) magnets, which support high magnetic flux with controlled thermal rise and help the motor maintain output in a compact frame. A Viton shaft seal protects the output shaft area from contamination, and the motor uses an English mounting interface that matches common inch-based machinery frames. The standard housing also completes the magnetic circuit around the rotor, and that arrangement supports stable operation in packaging, printing, and general automation equipment.
